08/29/23 21:40:1838.3030-74.6450JT- LF tonals with harmonics, approx every 5s repeated in some series, isolated in other places. Likely non-biological noise but doesn't necessarily look like vessel noise. All spp-ND.
08/29/23 22:40:1838.3030-74.6450JT_ LF tonals with harmonics continue in this period, some misclassified as FW, but INI is closer to 5s so FW-ND.
08/29/23 23:40:1838.3030-74.6450JT-the LF PTs in this period look more like typical non-biological noise with some freq modulation and artifact. All spp-ND.
